I personally never have had a problem with the ProTek bearings. I have been using them for a few years now in my 1/8 scale Losi buggy and truggy. I would recommend them to all.

Horrible, they didn't last a race weekend, one came totally apart and I couldn't finish my main. I don't have this problem with the stock Losi bearings. The real bargain is spending the money on good bearings!
